Tokyo Disneyland in July

April brings cherry blossoms and massive crowds. The park decorates every corner with sakura themes, but you'll wait 90 minutes for Space Mountain. May offers the best weather without the flower-viewing chaos. October and November give you Halloween decorations and comfortable temperatures. The Halloween parade runs twice daily, and cast members wear costumes. But avoid the actual Halloween weekend - it's shoulder-to-shoulder crowded. Winter means shorter lines but cold weather. January sees the fewest crowds, especially mid-week. Bring layers - Tokyo's winter wind cuts through everything. Summer brings festivals and extended hours, but also humidity that makes waiting in line miserable.
